Answer:
e. Check the order and the injection again, and then administer the injection
Step-by-step explanation:
One can easily administer a wrong injection in this type of scenario that is described in the question. A wrong administration of drug could occur if I miss the order as a result of the tendency for me to have forgotten the initial injection and order I had in mind or the right dose to be given, during the course of having to abandon the patient to attend to an emergency case.
Therefore, to be on a safer side, checking the order again, and then administering the injection is the right thing to do when I return. This is to ensure precaution in administration of injection to avoid errors.
